Electronic Theses and Dissertations

This research investigates the political economy of Nicaragua's development, with specific emphasis on Venezuela and China's influence, energy policy, and environmental and social justice related to the Nicaragua canal. The first section focuses on the political economy of the current Ortega administration in Nicaragua, as part of the return of left-leaning leadership in Latin America since the early 2000s. This study examines the Ortega administration's selective interpretation of the concept of imperialism and its effect on the environment as it pertains to US interests, Venezuelan oil financing and socialist rhetoric, and China's control over a large piece of Nicaraguan territory …

A Shifting Island Landscape: Changes In Land Use And Daily Life In The 19th And 20th Century Village Of Inishark, Co. Galway, Ireland, Lauren Marie Couey

Electronic Theses and Dissertations

This thesis investigates changes to village spatial arrangement and land use patterns in the nineteenth and twentieth century village of Inishark, Co. Galway, Ireland. To understand how spatial changes within the historic village were shaped by interactions between villagers and outside groups, including landlords and government agencies, a landscape approach was utilized. An examination of historic maps, valuation documents, and Irish Census documents, combined with ground-penetrating radar (GPR) survey and archaeological excavation, were used to understand how historical pressures impacted island life. Inishark's geographic isolation creates a unique case study to understand the impact of historical pressures on rural Irish …

Grassroots Relief: Informal And Community-Based Response To Extreme Weather Events From Occupy Sandy To The Cajun Navy, Gordon Douglas, Eric Klinenberg, Liz Koslov

Faculty Publications, Urban and Regional Planning

This study examines the role that local grassroots efforts play in disaster response and recovery. Drawing on findings from an ongoing research project on the experience of Hurricane Sandy in New York City since 2012 as well as new data from more recent hurricanes and other events, we show how volunteers, community-based organizations, and activist groups often play an important role in both immediate response and longer-term recovery efforts. Many communities hit hard by Sandy and other disasters were significantly aided by locally organized and 'informal' responses, often from groups that initially had nothing to do with emergency preparedness (community …

Integrated Analysis Of The Value Of Wetland Services In Coastal Adaptation; Methodology And Case Study Of Hampton-Seabrook Estuary, New Hampshire, Paul Kirshen, Semra Aytur, David M. Burdick, Diane Foster, Tom Lippmann, Ellen Douglas, Sydney Nick, Chris Watson

Jackson Estuarine Laboratory

The present impacts from coastal storms and high tides grow significantly over time due to SLR even over the relatively short period to 2060. Hydrodynamic model simulations of storm surge with and without sea level rise scenarios show that although flooding and inundation increases with increasing subtidal forcing and higher sea level, dissipation of the tide and storm surge in the estuary channel somewhat limits the maximum inundation that might otherwise be expected in the back marsh areas. The estuary is dominated by high marsh, which lies high in the intertidal zone and by 2060 it will convert to mostly …

The Political Biogeography Of Migratory Marine Predators, Autumn-Lynn Harrison, Daniel Costa, Arliss Winship, Scott Benson, Steven Bograd, Michelle Antolos, Aaron Carlisle, Heidi Dewar, Peter Dutton, Salvador Jorgensen, Suzanne Kohin, Bruce Mate, Patrick Robinson, Kurt Schaefer, Scott A. Shaffer, George Shillinger, Samantha Simmons, Kevin Weng, Kristina Gjerde, Barbara Block

Faculty Publications, Biological Sciences

During their migrations, marine predators experience varying levels of protection and face many threats as they travel through multiple countries’ jurisdictions and across ocean basins. Some populations are declining rapidly. Contributing to such declines is a failure of some international agreements to ensure effective cooperation by the stakeholders responsible for managing species throughout their ranges, including in the high seas, a global commons. Here we use biologging data from marine predators to provide quantitative measures with great potential to inform local, national and international management efforts in the Pacific Ocean. We synthesized a large tracking data set to show how …

Paleoflood Hydrology And Basin Morphometric Characteristics Related To Flooding In The Colorado Front Range, Natalie Trivino

Electronic Theses and Dissertations

Flooding hazards are common in the Colorado Front Range due to the steep, complex terrain of the mountains where waters quickly spill out onto the most populated region of Colorado. This region has experienced numerous catastrophic floods, such as the 2013 Front Range Floods, the Fort Collins Flood of 1997, and the Big Thompson Canyon Flood of 1976 to name a few. The objective of this study was to analyze basin morphometric characteristics of several drainage basins throughout the Colorado Front Range South Platte River tributaries and determine how these characteristics relate to extreme flooding. This was done through three …

An Investigation Of The Performance Of Urban Rail Transit Systems On The Corridor Level: A Comparative Analysis In The American West, Daniel Zimny-Schmitt

Electronic Theses and Dissertations

Since the 1980s, significant investments have been made in urban rail transit across the United States, particularly using light rail technology. Most of these light rail systems have been built in Sunbelt cities which no longer had legacy rail systems. As a result, they were constructed using a building blocks approach, being funded corridor by corridor. Most research, however, on urban rail performance has taken place at the system-wide level, leaving a significant gap at the level of the transit corridor. This research examined nineteen urban rail corridors in Denver, Salt Lake City, and Portland. A performance score was constructed …

Social Medicine And International Expert Networks In Latin America, 1930–1945, Eric D. Carter

Faculty Publications

This paper examines the international networks that influenced ideas and policy in social medicine in the 1930s and 1940s in Latin America, focusing on institutional networks organised by the League of Nations Health Organization, the International Labour Organization, and the Pan-American Sanitary Bureau. After examining the architecture of these networks, this paper traces their influence on social and health policy in two policy domains: social security and nutrition. Closer scrutiny of a series of international conferences and local media accounts of them reveals that international networks were not just ‘conveyor belts’ for policy ideas from the industrialised countries of the …

Expansion Of Major Urban Areas In The Us Great Plains From 2000 To 2009 Using Satellite Scatterometer Data, Lan H. Nguyen, Son V. Nghiem, Geoffrey M. Henebry

GSCE Faculty Publications

A consistent dataset delineating and characterizing changes in urban environments will be valuable for socioeconomic and environmental research and for sustainable urban development. Remotely sensed data have been long used to map urban extent and infrastructure at various spatial and spectral resolutions. Although many datasets and approaches have been tried, there is not yet a universal way to map urban extents across the world. Here we combined a microwave scatterometer (QuikSCAT) dataset at ~1 km posting with percent impervious surface area (%ISA) data from the National Land Cover Dataset (NLCD) that was generated from Landsat data, and ambient population data …

No. 09: The State Of Household Food Security In Nanjing, China, Zhenzhong Si, Taiyang Zhong

Hungry Cities Partnership

This report on the state of food security in Nanjing, China, is based on a 2015 city-wide survey conducted by Nanjing University and the Hungry Cities Partnership. The research found that most of the city’s residents are food secure, with access to desirable foods and high dietary diversity throughout the year. Nanjing has a high level of economic development, low unemployment, and spatially dense food supply networks. However, a high average level of food security obscures the finding that about one household in five is food insecure according to the Household Food Insecurity Access Prevalence indicator. Female-centred households, households that …

No. 15: The Food Security Implications Of Gendered Access To Education And Employment In Maputo, Cameron Mccordic, Liam Riley, Inês Raimundo

Hungry Cities Partnership

The multiple linkages between gender and household food security in cities have been observed in diverse settings, at multiple scales, and through a variety of disciplinary lenses. The Hungry Cities Partnership is rooted in the importance of inclusive growth of cities, which includes a fundamental concern with genderbased injustices that reduce inclusivity, sustainability and food security by underpinning structural poverty. This discussion paper is motivated by the gap in policy-ready quantitative data needed to identify the ways in which gender inequality, food insecurity, and public policy are interconnected. Analysis of the 2014 survey of household food security in Maputo identified …

Data: Pre-Fire Disturbance History Modulates Relationships Between Ground Cover And Post-Fire Conifer Regeneration, Nathan Gill, Dan Jarvis, Tom Veblen, John Rogan, Dominik Kulakowski

Student Works

Understory vegetation and ground cover drive many important ecosystem processes, including tree seedling regeneration. The exact effect of ground cover on tree seedling establishment, survival, and growth depends on biophysical context. In subalpine forests, this context is largely determined by disturbances such as beetle outbreak, blowdown, and fire. Compounded disturbances that overlap in short succession can alter stand properties and trajectories in ways that are not predictable from the additive impact of individual disturbances. The aim of this study is to examine how compounded Dendroctonus rufipennis (spruce beetle; SB) outbreak followed by fire and compounded wind blowdown followed by fire …

From Icon Of Empire To National Emblem: New Evidence For The Fallow Deer Of Barbuda, Sophia Perdikaris, Allison Bain, Sandrine Grouard, Karis Baker, Edith Gonzalez, A. Rus Hoelzel, Holly Miller, Reaksha Persaud, Naomi Sykes

School of Global Integrative Studies: Faculty Publications

Barbuda and Antigua’s national animal is the fallow deer, Dama dama dama, a species native to the eastern Mediterranean that has been transported around the world by people during the last 8000 years. The timing and circumstances by which fallow deer came to be established on Barbuda are currently uncertain but, by examining documentary, osteological and genetic evidence, this paper will consider the validity of existing theories. It will review the dynamics of human–Dama relationships from the 1500s AD to the present day and consider how the meaning attached to this species has changed through time: from a …

Accuracy Of Unmanned Aerial System (Drone) Height Measurements, Daniel Unger, I-Kuai Hung, David Kulhavy, Yanli Zhang, Kai Busch-Peterson

Faculty Publications

Vertical height estimates of earth surface features using an Unmanned Aerial System (UAS) are important in natural resource management quantitative assessments. An important research question concerns both the accuracy and precision of vertical height estimates acquired with a UAS and to determine if it is necessary to land a UAS between individual height measurements or if GPS derived height versus barometric pressure derived height while using a DJI Phantom 3 would affect height accuracy and precision. To examine this question, height along a telescopic height pole on the campus of Stephen F. Austin State University (SFASU) were estimated at 2, …
